Creates packages that can be loaded into a running project.
	
	
		The [PCKPacker] is used to create packages that can be loaded into a running project using [method ProjectSettings.load_resource_pack].
		[codeblocks]
		[gdscript]
		var packer = PCKPacker.new()
		packer.pck_start("test.pck")
		packer.add_file("res://text.txt", "text.txt")
		packer.flush()
		[/gdscript]
		[csharp]
		var packer = new PCKPacker();
		packer.PckStart("test.pck");
		packer.AddFile("res://text.txt", "text.txt");
		packer.Flush();
		[/csharp]
		[/codeblocks]
		The above [PCKPacker] creates package [code]test.pck[/code], then adds a file named [code]text.txt[/code] at the root of the package.
	
	
	
	
		
			
			
			
			
			
				Adds the [param source_path] file to the current PCK package at the [param pck_path] internal path (should start with [code]res://[/code]).
			
		
		
			
			
			
				Writes the files specified using all [method add_file] calls since the last flush. If [param verbose] is [code]true[/code], a list of files added will be printed to the console for easier debugging.
			
		
		
			
			
			
			
			
			
				Creates a new PCK file with the name [param pck_name]. The [code].pck[/code] file extension isn't added automatically, so it should be part of [param pck_name] (even though it's not required).
